FUEL-TANK OUTLET.

Specification of Letters Patent. Patented July 26, 1921.

Application filed May 8, 1920. Serial 'No. 379,878.

To all 007mm it may concern:

Be it known that l, FRANK P. Ommmunn, n eil 'en of the United States, residing at Il nipe ial, in the county of Chase and State of Nebraska, have invented eertain new and useful Improvements in Fuel-Tank Outlets, of which the following: is a speeiliration, relerenre being: had to the accompanying drawings.

This invention relates to certain improvements in fuel tank outlets and has relation more partienlarl y to a. device of this gene -al character esperially designed and adapted for use in connection with the carbureter of an internal combustion engine, and it is an objeet of the invention to provide novel and lIIIPIUVQtl means whereby the fuel below a 1n'edetennined level within the tank constitntes a reserve supply, and which reserve supply may be drawn upon for use at will.

.i\nother object of the invention is to pro- 'vide a novel and improved outlet for a fuel tank embodying a valve comprising two relatively movable members, each of said members being, tubular With the bores thereof substantially in continuity, each of said members being provided with a port in eonneotion with its bore, one of said members:

being provided with a second port adapted to register with the port of" the seeond memher, the flaw through the port of. the second member being under control of the first member.

An additional object of the invention is to provide a novel and improved outlet of actor comprising two tnbn lat-members having their bores substantially in rontinnity one of said members being rota'table relative to the other, each of said members hreinn provided with a port in communieation with its bore, the rotatable memher in one positionserving to close the port in the second member and to open said port when in a second position, together with means for imparting rotation to the rotary member, said means operating automatically to maintain said rotary member at snbstantially the limit of its movement in either d1- reotion.

lit is also an object of the invention to provide a novel and improved outlet of this general character ineluding two relatively inovaliile tubular members eaeh provided with a port, one of said members being movable to open or close the port of the second member and whereinmeans are provided for limiting the relative n'iovenlent of the men hers in one direetion and positively assure the Inaintena'nve of the port in the second member positively closed.

The invention consists in the details of eonstrurtion and in the eomliiination and arrangrtnnent of the several parts oi my improved fuel tank outlet whereby certain inn portant advantages are attained and the deviee remlered simpler, less expensive and otherwise more convenient and advaniatgeons for user an will be hereinafter more fully forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better umlerstooth'l will now proeeedfto (lo-- scribe the same with reference to the aceom pan ringr dra'wingna wherein:

Figure 1 is a. fragmentary view, partly in Sertion and partly in elevation illustrating an outlet eonstrneted in aeeordanee with the embodiment, oi my invention.

Fig. 2 is a view in top plan and'oit a dia granunatiral character illustrating the op- 'eratinn means for the outlet as herein embodied, a second position being indicated by dotted lines.

Fig. 3 is an enlarged transverse sectional view taken through the lower portion of the outlet showing the port for the reserve supply closed. and

Fig. t is a view in plan of one oi" the sup-- porting; members for the outlet as herein set forth.

As disclosed in the aeeompanying drawings, T denotes a fuel supply tank of a eonrentional type and whirh has extending in wardly thereof through its lower wall a rela ti'vely short outlet pipe or eylindrieal easing I. The pipe or casing l is threaded through the wall of the tank T, or more artienlarly the reint'oreing member 2, defining opening 3 in the wall of the tank, throughwhieh said casing the pipe 1 is disposed.

The outer or exterior end portion of, the easing or pipe .l is enlarged whereby a sl'ioulder -l is provided and which shoulder limits the extent of insertion otth'e casing or pipe l within the tank T. The outer or exterior end portion of the. :asmg or pipe 1 also has ite here enlarged as, at 5, and with which enla portion is adapted to be coupled a sediment bulb, it prefierred or a pipe line leading directly from said casing or pipe 1 to the carbureter of the internal combastion engine.

The portion of the casing or pipe 1 inserted Within the tank T is provided in a wall thereof with a port 6, said port being positioned immediately adjacent the lower portion of the wall of the tank T, as is clearly illustrated in Fig. 1 of the accompanying drawings. I

7 denotes a tubular valve stem of such diameter to permit its insertion within the tank T from below and through the opening 3. The upper end portion of the stem 7 is provided with a reduced extension 8 which, when the stem 7 is applied, is adapted to extend exteriorly of the tank T through an opening 9 in the top wall of the tank T and in vertical alinement with the opening 3. The stem is inserted within the tank Thefore the casing or pipe 7 is applied. Before the stem 7, or more particularly the extension 8 is applied, the plate or washer 10 is inserted within the tank T through'the opening 3, said plate or washer 10 being of such diameter as to readily permit its passage through said opening. After the-plate or washer 10 has been applied within the tank T the extcnsion 8 of the stem is inserted through the opening 3 and through the opening 11 of the plate or washer 10. The stem 7 is then forced upwardly through the tank T until the extension 8 is disposed exteriorly of the tank T through the opening 9. The plate or washer 10 will beearried upwardly by contact with an annular shoulder 12 surrounding the inner end of the extension 8. After this assembly a second plate'or washer 15 is disposed around the exterior 1 portion of the extension 8. The washer or plate 8 is substantially the same configuration and dimensions as the washer or plate 10 and said plates or washers 10 and 15 when applied are in overlying relation. The bolts 16 or other fastening means are then operatively engaged with the end portions of the plates or washers 10 and 15 and dispo'sed through the adjacent wall of the tank T. By this means an effective bearing for the upper portion of the stem 7 is provided. 'It is also preferred that the gaskets 17 be interposed within each of the washers 10 and 15 and the adjacent face of the tank T, and which Washers for convenient assembly may be adhesively or otherwise secured to the washers or plates .10 and 15, although this arrangement is not imperative.

The lower portion 18 of the stem 7 is re duced and said reduced portion has threaded engagement within the casing or pipe 1 and when applied said reduced portion 18 is of such length to extend across the port 6 here .iIlbGfOl'E referred to. .The extension 18 is aisozprovided with a port 19 which upon partial rotation in one direction of the stem 7 is adapted to register with the port (3 in the casing or pipe 1. The stem 7 all a predetermined distance above the extension 18 is provided with a port 20 through which the fuel within the tank flows into the stem 7 and out through the casing or pipe 1 until the level of said fuel falls before the port 20. By this means a reserve supply of fuel is provided and which reserve supply pan be used at will by rotating the stem 7 to bring the port 19 in register with the port (31 This provision of the reserve supply is of particular advantage in such localities where ill ing stations or other sources of fuel supply, are relatively a great distance apart. \Vhen the level of the fuel within the tank T drops within the port 20, the sputtering of the engine will give notice to the driver of the motor driven vehicle that the supply oi fuel is running low, whereupon lhc driver will adjust the stem 7 to bring the ports 6 and 19 into register. whereby the reserve supply of fuel may be used and which reserve supply is preferably in such quantity as to permit the car to be driven for a considerable distance so that under ordinary conditions suliicicnt opportunity will be given to reach the filling station or other source of fuel supply.

Fixed to the exterior end portion of the extension 8 is a crank or rock arm 21 and pivotly engaged with the outer end portion of such crank or rock arm .21 is an end por tion of the operating arm or lever .22 terminating at its opposite end into an annular member or loop .225. The annular mcmher or loop 23 provides means whereby the requisite pulling may be impressed upon the rod or arm 22 when required. The outer end portion of the rod or arm 22 is slidahly disposed through an opening 251- provided in the member-Q5 positioned in desired location with respect to the tank '1 and which member 25 in the present embodiment oi my invention constitutes the front panel of the scat structure such as comprised in the well known Ford car and wherein the fuel tank is housed within said seat structure.

Mounted upon the inner end portion of the rod 'or arm 22 and at a point in close proximity to the crank or rock arm 21 is a stop 2213. Bearing against the stop 26 is an end portion of the expa-nsihlc member 527 herein disclosed as a coil spring encircling the rod or arm 22. The opposite end por tion of the member or spring 27 is in contact with a disk 28 or the like mounted onl the rod or arm 22 and which is inl contact with the inner -face of: the member-25. The expansible member or spring 27 operates to constantly urge the crank or rock arm 21 in wardly whereby the stem 7 is maintained in a' position whereby the port 6 is either fully openedor closed without any inlnrmediate p noon mijimtmont.
